Description

The present invention relates to a paper box, and more particularly to a paper box in which the lid and the main body are separable, and the lid is locked to the main body when the lid is opened to prevent the paper box from falling off.

Some paper boxes, which are assembled by folding a paper blank sheet cut into a predetermined shape, make it easy to take out the contained items and make it possible to display the contained items in a good-looking state. Further, in some such paper boxes, the lid and the main body are separately formed (see, for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 2007-223623

However, the paper box as in Patent Document 1 is not intended to be used multiple times for the purpose of temporary packaging of the contents, and it is necessary to completely remove the lid from the main body when opening the paper box. Therefore, it was not configured so that the lid and the main body could be handled integrally and the opening and closing could be performed smoothly.

Therefore, a paper box such as Patent Document 1 is not suitable for storing, for example, a trading card or the like that is repeatedly required to be stored and taken out. Also, with trading cards, the lid of the paper box is integrated with the main body so that the card is often taken out at a table or the like for use or viewing, so that the lid does not get in the way or is not lost. There is a need to deal with such needs, but it was not possible to meet such needs.

Therefore, the present invention provides a paper box that can handle the lid and the main body integrally, can smoothly open and close the lid with respect to the main body, and is suitable for storing articles that need to be repeatedly stored and taken out. The purpose is to provide.

In order to achieve the above object, the paper box of the present invention has a main body formed by assembling one blank sheet for a main body into a substantially rectangular shape with one side open, and one blank sheet for a lid. In a paper box composed of a lid formed by being assembled in a substantially rectangular shape with an opening, the blank sheet for the main body is connected to the back surface portion base paper piece of the main body and the rear surface portion base paper piece of the main body via a crease line. It is a substantially U-shaped notch provided across the folded paper piece on the rear surface of the main body, the base paper piece on the rear surface of the main body, and the folded paper piece on the rear surface of the main body, and both ends of the U-shape are the main body. The main body is provided with a cut line located on the side of the rear surface portion base paper piece and a hinge wire formed by a crease connecting both ends of the cut line, and the main body is the main body with respect to the main body rear surface portion base paper piece. The back surface of the main body is formed by folding the folded piece of paper on the side rear surface inward around the crease line, and the portion surrounded by the cut line is folded outward around the hinge line to form the tongue. A piece-shaped engaging piece is formed, and the engaging piece has a tip portion in which a portion separated from the folded paper piece on the rear surface of the main body is folded outward about the crease line, and the lid body. The blank sheet includes a lid rear surface base paper piece, a lid rear surface folded paper piece serially connected to the lid rear surface base paper piece via a crease line, and a part of the lid rear surface folded paper piece. The lid is provided with a cutout hole cut out to a size that allows the tip of the engaging piece to be inserted, and the lid has a folded paper piece on the rear surface of the lid about the crease line with respect to the base paper piece on the rear surface of the lid. By folding inward, the rear surface portion of the lid is formed, and a pocket-shaped engagement having the cutout hole as an insertion port in the gap between the rear surface portion base paper piece of the lid body and the folded paper piece of the lid rear surface portion. It is characterized in that a part is formed.

Further, the length from the folded position of the cut line to the crease line connecting the main body rear surface base paper piece and the main body rear surface base paper piece is the length from the hinge line to the main body rear surface base paper piece and the main body rear surface portion. It is also characterized by being formed so as not to exceed the length up to the crease line that connects the base paper pieces.

Further, the hinge wire is positioned so that the distance between the hinge wire and the upper side of the front surface portion of the main body does not exceed the distance between the front surface portion of the lid body and the rear surface portion of the lid body. It is also characterized in that the front surface portion of the main body is formed lower than the rear surface portion of the main body.

Further, a notch is provided at the lower end of the front surface portion of the lid body, the height of the rear surface portion of the lid body is shorter than the height of the rear surface portion of the main body, and the inside of the main body. It is also characterized by having a partition that divides the space inside the main body.

According to the paper box of the present invention, the lid formed from the blank sheet for the lid is attached to the main body formed from the blank sheet for the main body, and the tip portion of the engaging piece provided on the rear surface portion of the main body is formed. It is attached to the main body by being folded outward at the position of the upper side of the rear surface of the main body and having an engaging portion having an insertion port into which the tip of the engaging piece can be inserted on the inner surface of the rear surface of the lid. The lid can be pulled up from the main body to be engaged, and by opening the lid in the engaged state, the lid can be opened while being connected to the main body, and the opened lid can be opened. By rotating the hinge wire forward around the axis and then pushing it down, the lid can be reattached to the main body, so the lid can be opened and closed smoothly with respect to the main body, and the accommodation can be repeated. And can be easily taken out.

In addition, since the lid can be opened while maintaining the engagement state with the main body, the lid can be handled integrally without falling off from the main body even when the paper box is sufficiently opened, so that the main body and the lid can be separated. By being separated and formed, it is possible to reduce the demerit that the lid becomes an obstacle or is lost when the paper box is opened.

Further, in the blank sheet for the main body, the length from the folded position of the substantially U-shaped cut line to the crease line connecting the rear surface portion base paper piece of the main body and the rear surface portion base paper piece of the main body is from the hinge line to the main body. Since it is formed so as not to exceed the length up to the crease line connecting the rear surface base paper piece and the main body rear surface base paper piece, when the main body is assembled, the inner surface of the main body rear surface is restricted to have a concave shape. Since a portion is formed to regulate the movement of the engaging piece inward and prevent it from falling inward, the tip of the engaging piece is positioned outside the rear surface of the main body regardless of the accommodation state of the main body. , The lid can be securely inserted into the insertion port of the engaging portion of the lid, and the lid can be easily engaged with the main body, so that the main body and the lid can be handled more integrally. ..

In addition, the distance between the hinge wire and the upper side of the front surface of the main body is positioned so as not to exceed the distance between the front surface of the lid and the rear surface of the lid, and the front surface of the main body is larger than the rear surface of the main body. Since the lid is formed low, the front surface of the lid does not get caught in the front surface of the main body when the lid is opened, so that the lid can be opened and closed more smoothly with respect to the main body.

In addition, since the front surface of the main body is formed lower than the rear surface of the main body, the upper front surface of the contained object is not covered by the front surface of the main body, so that it is easy to see even when the contained object is housed in the main body. In addition to the fact that there is a notch on the upper side of the rear surface of the main body due to the provision of the engaging piece, and there is a part that is not covered on the upper rear surface of the contained object, the upper part of the contained object contained in the main body is front and back. Since it is easy to pinch from the direction, it is easy to put in and take out the contents.

Further, a notch is provided at the lower end of the front surface portion of the lid body, and the height of the rear surface portion of the lid body is shorter than the height of the rear surface portion of the main body, so that the lid body is attached to the main body. Even in the state, there is a region that is not covered by the front surface of the lid in a part of the lower end of the front surface of the main body, and the entire lower end of the rear surface of the main body is not covered by the rear surface of the lid. Since it can be held by the body, it is possible to easily grasp the main body and pull up the lid body, and the lid body can be opened and closed more smoothly with respect to the main body.

Since a partition that divides the space inside the main body is arranged inside the main body, the space inside the main body can be effectively utilized according to the size of the contents, and the storage capacity of the paper box can be increased.

It is an exploded perspective view which shows the whole structure of the paper box of this invention. It is a front view of the main body which arranged the partition inside.

9 is a front view showing a state of a paper box 11 in which a partition 14 is arranged in a main body 12 and a lid 13 is attached, FIG. 10 is a sectional view taken along the line XX of FIG. 9, and FIG. 11 is a cross-sectional view of the paper box. , Is a front view showing a state in which the lid body attached to the main body is pulled up, FIG. 12 is a cross-sectional view of XII-XII of FIG. 11, and FIG. 13 is a main body by rotating the lid body of FIG. 12 backward. It is a side sectional view showing how the paper box opens with the lid and the lid connected.

As shown in FIGS. 9 and 10, the lid 13 is attached so as to cover the main body 12. That is, when the lid 13 is attached to the main body 12, the inner surface of the lid front surface portion 13b is adjacent to the outer surface of the main body front surface portion 12b, and the inner surface of the lid rear surface portion 13c is adjacent to the outer surface of the main body rear surface portion 12c. The inner surfaces of the lid side surface portions 13d and 13d are adjacent to the outer surfaces of the main body side surface portions 12d and 12d, respectively.

In this state, the engaging piece 15 does not fall inward because the movement of the engaging piece 15 is restricted by the restricting portion 15d inward, and the tip portion 15a opens in a folded state due to the restoring force of the paper. Since it is urged, it comes into contact with the inner surface of the rear surface portion 13c of the lid.

Therefore, as shown in FIGS. 11 and 12, when the lid 13 attached to the main body 12 is pulled up, the engaging portion 16 is also pulled up, and the height position of the insertion port 16a is the height of the engaging piece 15. When the position is reached, the tip portion 15a of the engaging piece 15 is inserted into the pocket-shaped engaging portion 16 from the insertion port 16a and engaged, so that the main body 12 and the lid 13 are connected and engaged. Become a state.

At this time, the length F ₂ of the tip portion 15a and the depth F ₃ of the engaging portion 16 are provided so as not to exceed the length F ₁ from the hinge wire 15b to the upper side of the rear surface portion 12c of the main body. Therefore, the rear surface portion 13c of the lid does not become an obstacle when rotating backward around the hinge wire 15b.

As shown in FIG. 13, the main body 12 and the lid 13 are engaged with each other by opening the lid 13 engaged with the main body 12, that is, rotating the lid 13 backward about the hinge wire 15b as an axis. The lid 13 is opened while maintaining the combined state.

Here, the length W ₂ in the front-rear direction of the lid 13 is slightly longer than the length W ₁ in the front-rear direction of the main body 12, and the distance W formed between the hinge wire 15b and the upper side of the front surface portion 12b of the main body 12b. Since ₃ is positioned so as not to exceed the length W2 in the front _- rear direction of the lid 13, the front surface portion 12b of the main body overlaps on the trajectory of the front surface portion 13b of the lid when opening the lid 13. It is prevented from getting caught.

As a result, the upper part of the main body 12 can be made not blocked by the lid 13, and the paper box 11 can be sufficiently opened.

As described above, according to the paper box 11 of the present invention, the lid 13 formed from the blank sheet 70 is mounted on the main body 12 formed from the blank sheet 30 so as to cover the main body 12 and is provided on the rear surface portion 12c of the main body. The tip portion 15a of the engaging piece 15 is folded outward at the position of the upper side of the rear surface portion 12c of the main body, and has an insertion port 16a into which the tip portion 15a of the engaging piece 15 can be inserted into the inner surface of the rear surface portion 13c of the lid. By providing the engaging portion 16, the lid 13 attached to the main body 12 can be pulled up from the main body 12 to be in an engaged state, and the lid 13 is connected to the main body 12 by opening the lid 13 in the engaged state. The lid body 13 can be opened as it is, and the lid body 13 can be reattached to the main body 12 by rotating the opened lid body 13 forward around the hinge wire 15b and then pushing it down. Therefore, the lid 13 can be smoothly opened and closed with respect to the main body 12, and the contents can be repeatedly stored and taken out.

Further, since the lid 13 can be opened while maintaining the engagement state with the main body 12, the lid 13 can be handled integrally without falling off from the main body 12 even when the paper box 11 is sufficiently opened. By forming the lid 13 and the lid 13 separately, it is possible to reduce the demerit that the lid 13 gets in the way or is lost when the paper box 11 is opened.

Further, in the blank sheet 30, the length F _{2 from the folded position of the substantially U-shaped cut line 48 to the fold line 46 is formed so as not to exceed the length F 2 from} the hinge line 15b to the fold line 46. Therefore, when the main body 12 is assembled, a concave restricting portion 15d is formed on the inner surface of the main body rear surface portion 12c to restrict the movement of the engaging piece 15 inward to the main body 12 and prevent it from falling inward. Therefore, regardless of the accommodating state of the main body 12, the tip portion 15a of the engaging piece 15 is positioned outside the rear surface portion 12c of the main body, and the fitting portion 16 of the lid 13 is securely inserted into the insertion port 16a. This makes it easier to engage the lid 13 with the main body 12, so that the main body 12 and the lid 13 can be handled more integrally.

Further, the distance between the hinge wire 15b and the upper side of the front surface portion 12b of the main body is positioned so as not to exceed the distance between the front surface portion 13b of the lid and the rear surface portion 13c of the lid, and the front surface portion 12b of the main body is from the rear surface portion 12c of the main body. Since the lid 13 is formed low, the front surface portion 13b of the lid body does not get caught in the front surface portion 12b of the main body when the lid body 13 is opened, so that the lid body 13 can be opened and closed more smoothly with respect to the main body 12. can.

Further, since the front surface portion 12b of the main body is formed lower than the rear surface portion 12c of the main body, the upper front surface of the contained object is not covered with the front surface portion 12b of the main body, so that it is easy to visually recognize even when the contained object is housed in the main body 12. Moreover, by providing the engaging piece 15, a notch 15c is formed on the upper side of the rear surface portion 12c of the main body, and there is a portion that is not covered on the upper rear surface of the contained object. Since the upper part of the container is easy to hold from the front and back, it is easy to put in and take out the contents.

Further, since a notch 17 is provided at the lower end of the lid front surface portion 13b and the height of the lid rear surface portion 13c is shorter than the height of the main body rear surface portion 12c, the lid body 13 is the main body. Even in the state of being mounted on the main body 12, there is a region not covered by the lid front surface portion 13b in a part of the lower end of the main body front surface portion 12b, and the entire lower end of the main body rear surface portion 12c is not covered by the lid rear surface portion 13c. Since the front surface portion 12b of the main body and the rear surface portion 12c of the main body can be pinched by fingers, the main body 12 can be easily grasped and the lid 13 can be easily pulled up, and the lid 13 can be opened and closed more smoothly with respect to the main body 12. ..

Since the partition 14 that divides the space inside the main body 12 is arranged inside the main body 12, the space inside the main body 12 can be effectively utilized according to the size of the contents, for example, a trading card. The space can be suitable for accommodating the deck.

By the way, with the lid 13 attached to the main body 12, when the lid 13 is pulled up while inserting an elongated object such as a finger or a measure into the gap between the rear surface portion 12c of the main body and the rear surface portion 13c of the lid, the engaging piece 15 is engaged. Since the tip portion 15a of the above is prevented from being inserted into the engaging portion 16 from the insertion port 16a, the main body 12 and the lid 13 do not engage with each other, and the lid 13 can be removed from the main body 12.

The present invention is not limited to the above-mentioned embodiment, and various modifications can be made within the scope of the invention. For example, in this embodiment, the internal space of the paper box body is provided with a partition that divides the internal space into two, but the partition is not limited to the one that divides the internal space into two, and the internal space is divided into three according to the contents. It may be divided into the above, or the partition may be eliminated.
